Orange County NC <br />30 <br />Radio Communication Tower and System Infrastructure Upgrade <br />RF Coverage and Sites/Towers <br />2.2.E ehatharn Mountain Site <br />Currently the Fire Station paging station and antenna are at the 1000 ft. level on the <br />Chatham Mountain tower. At this height the FCC license limits RF power output and <br />effective radiated power. As discussed with Orange County, a height of 150 ft. would be <br />more appropriate for obtaining paging coverage in the southern part of the County. Also, <br />the use of a directional antenna will enhance coverage into Orange County. <br />Also, a site at StarPoint Storage was reviewed, to be used in lieu of the Chatham site. <br />This site provides better RF coverage into the southeast corner of Orange County, <br />however, RF coverage into the southwest corner is decreased. FE prepared RF <br />Coverage maps for the StarPoint Storage site as well, which can be found in Section <br />2.2.5. <br />Following discussion with Orange County, FE reviewed and analyzed the Chatham site <br />further, to determine if adjusting the antenna height and antenna orientation would <br />result in improved VHF RF coverage into the southeast and southwest corners of the <br />County. <br />By raising the antenna height to 200 ft., FE found that RF coverage could be improved <br />in the southeast corner of the County, while not significantly reducing coverage in the <br />southwest corner. Figure 16 shows the predicted VHF RF coverage using an antenna <br />height of 200 ft. at the Chatham Mountain site. <br />VHF paging coverage has been predicted and plotted, as shown in Figure 14 through <br />16 below. <br />August 30, 2013 Page 29 of 51 <br />
